SPECIFICATXON forming part of Letters Patent No. 695,040, dated March 1 1, 1902. Application filed November 14, 1901. Serial No.18217232. (No model.)

To @ZZ Vwhom, t may conceive.-

Be it known that we, CLARE H. DRAPER and EDWARD S. STIMPsoN, citizens of the United States, and residents of Hopedale, county of Vorcester, State of Massachusetts, have invented an Improvement in lilling-Replenish` 2o mounted to rotate intermittently and in unison and holding between them a series of filling-carriers, the latter being transferred one by one to the shuttle by suitable transferring means. A circular disk is mounted at the outer end of and rotates with the feeder and is provided on its outer face with a stud, the filling ends being led from the several fillingcarriers over the periphery of the disk and thence to the stud, about which they are sego cured. The transfer of a filling-carrier to the shuttle sometimes causes breakage of the filling end before it can unwind with sufficient rapidity from the filling-carrier being transferred to the shuttle.

This invention has for its object the production of novel means for preventing such breakage of the filling ends by providing a surplus or slack portion of filling between the feeder and the filling-end-holding means, the

4o slack or surplus portion normally maintained taut being released instantly as the fillingcarrier is transferred to the shuttle.

The various novel features of our invention will be hereinafter described, and particularly pointed out in the following claims.

Figure l is a right-hand side elevation, partly broken out, of a sufficient portion of a loom and the filling-replenishing mechanism thereforto be understood with one embodiment of our invention applied thereto. Fig. 2 is a front elevation of the filling-replenish` ing mechanism shown in Fig. 1, some of the filling carriers and the filling ends being shown in dotted lines to illustrate the manner in which the slack or surplus portion of the filling is provided; and Fig. 3 is a perspective detail, detached, of means for positively releasing the filling at the time of transfer.

The loom-frame A, lay A3, the bunter C2 thereon, the self-threading shuttle S, of suitable construction, the stand A7, substantially circular in shape and secured upon and transversely to the breast-beam A40, and the filling-feeder may be and are substantially as shown and described in Patent No. 664,790, dated September 24, 1900, to which reference may be had.

flhe feeder comprises, essentially, two disks d d', connected to rotate in unison by a hub as, rotatably mounted on a stud as, fixedly mounted on the stand A7, the filling-carriers b (see dotted lines, Fig. 2, and full lines, Fig.

l) being held at their ends between the two disks. At the outer end of the feeder fillingend-holding means is provided comprising a disk b', provided with a stud b2, the hub of the disk being secured by a set-screw 5, FigfA 2, to a boss d20, projecting from the outer face of the disk or. The filling ends b3() are led from the periphery of the disk et to the periphery of the disk b and then down and wrapped around the stud b2; but between the two disks the filling ends are deflected from their direct paths by means to be described, so that when the threads are released between the two disks they will hang slack or provide a surplus portion to prevent shock due to too sudden strain on the filling at the time of transfer.

A disk m, having a series of peripheral notches mx equal in number to the fillingcarriers which may be carried in the feeder, is connected by arms m', Fig. 2, to a hub m2, which surrounds the boss d20 between the disk aand the adjacent end of the hub of the disk b', the latter having a notch or recess b therein to be entered by a lug m3, (shown only in Fig. 2,) projecting outwardly from the hub n2, so that the disk m, which we shall hereinafter designate as the slacksupporter, will rotate with the feeder and disk b'. Referring to Figs. 1 and 2,.it will be noted that the slack-supporter is set forward, as it were, so that its notches mx will be non-alined with the direct path ofa fillingthread between the disk a of the feeder and the disk b', and when the attendant places a filling-carrier in thel feeder he takes the filling end 530 and enters it into one of the notches mx and thence carries it over the disk b' and down tothe stud b2, wrapping the loose end around the latter, so that the filling ends will be deflected between the disks c b', as shown in Figs. 1 and 2. The diameter of the slack-supporteris somewhat larger than that of either of the disks a b to give an additional slack portion of thread at the proper time bythe radial deflection. During the normal operation of the loom the several filling ends will be held by the means hereinbefore described sufficiently taut to prevent entanglement one with another.

The stand A7 supports a fixed horizont-al stud f, on which is loosely mounted the hub f2 of an arm f, constituting the transferrer, as in the patents referred to, said transferrer being provided with a lateral arm 21, having a downturned end 22 to engage the tip of the filling-carrier at the time of transfer, the transferrer and arm 21 extending in between the disks of the feeder, as shown in Fig 2. A headed rocker-stud m12 is mounted on the downturned arm f3 of the transferrer, as in United States Patent No. 664,790, and by a spring 50, Fig. 2, the stud is normally turned in the direction of the arrow 12, Fig. -1, an arm m13, secured to the stud, having a lateral lug m14, against which rests the branch y2 of the shuttle-feeler yx, and a notched dog m15 is adjustably secured to the arm m13, said dog being movable into the path of the bunter C2 on the lay when a change of filling is to be effected, all in well-known manner. We have herein shown the stud f as extended tosupport the hub r-X'of a knock-off device, the same consisting of an arm 7s, secured in a boss 7c on the hub 75X and having its inner end extended toward the back of the loom and between the slack-supporter and the disk ct', the inner extremity of said arm Zo being preferably upturned' at 7a2. At

`its inner end the hub 76X, which is loosely mounted on the stud f, is provided with aradial arm 7c3, provided at its extremity with a lateral extension 7a4, extended toward the center of the loom and across the inner edge of the depending arm f3. The weight of the knock-off device normally maintains it in the position shown in Fig. 1, with the extension 104 resting against the edge of the depending arm f3, while the knock-off arm tprojects just above the filling end of the filling-carrier'next to be transferred from the feeder.

When the transferrer f is depressed from eamo-.1.ov

the position shown in Fig. l to engage and transfer the endmost filling-carrier of the series from the feeder to the shuttle, the knockoff device will simultaneously rock on the stud f, and the arm 7c will lightly hit the filling end just beneath it to cast it off or remove it from the notch mx in the-disk m, so that the said filling end will hang slack at the instant of transfer, and the slack or surplus portion so provided will be sufficient to obviate a breaking strain upon the filling as the shuttle is thrown from the box, or it may be as the filling-carrier is ltransferred to the shuttle. The automatic return of the transferrer to normal position after such transferrer acts,

` (see Fig. 1) on the stand A7 when the knockolf device operates to limit the rocking movement of the same and preventing the arm 7c from descending far enough to be hit by the lay or any moving part of the loom. When a filling-carrier is transferred from the feeder to the shuttle, the downward movement of the filling-carrier will of itself release the filling end from the slack-supporter, inasmuch as the filling merely rests upon the peripheral edge thereof; but any accidental sticking of the thread to the notched disk or sluggishness of release by the downward movement of the filling-carrier when transferred will be prevented by the knock-off device.

The construction is simple and effective, and a sufficient surplus portion of refilling is provided by the release of each filling end from the slack-supporter.

Our invention is not restricted to the precise construction and arrangement herein shown and described, as lthe same may be modified or rearranged invvarious particulars without departing froln the spirit and scope of our invention.
